Hurry I need some help, explain it too if you can
Two students, Robert and Jacob, simplify the expression 3(?? + 4x - 1)-(2x + 5), as shown below.
Robert
Jacob
Step 1 | = 3x2 + 12x - 3 - (2x + 5)
Jacob = 3x + 12x-1-(2x + 5)
Step 2 = 37+12r-3-2x+5
Jacob = 3x2 + 127-1-2-5
Step 3
3P + 10x + 2
Jacob = 3.rΒΊ + 10x - 6
3. The first error made in the simplification of the expression shown above was made by
A. Robert in Step 1
B. Jacob in Step 1
C. Robert in Step 2
D. Jacob in Step 2β
